ios – 是否接受UIWebView中的Cookie？

UIWebView将自动将Cookie存储在[NShttpCookieStorage sharedhttpCookieStorage]集合中,并且应该在应用程序启动期间在应用程序的所有其他UIWebView中可用.但是,UIWebView类不会自动存储应用程序启动之间加载的@L_673_12@的Cookie.当应用程序移动到后台时,您需要手动存储Cookie,并在应用程序返回到前台时重新加载值.

将以下代码放在AppDelegate类中：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //Other exisTing code

    [self loadhttpCookies];
    return YES;
}

- (void)applicationDidEnterBACkground:(UIApplication *)application
{
    //Other exisTing code

    [self savehttpCookies];
}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
    [self loadhttpCookies];
}

- (void)applicationWillTerminate:(UIApplication *)application
{
    //Other exisTing code
    [self savehttpCookies];
}

-(void)loadhttpCookies
{
    NSMutableArray* cookieDictionary = [[NSUserDefaults standardUserDefaults] valueForKey:@"cookieArray"];

    for (int i=0; i < cookieDictionary.count; i++)
    {
        NSMutableDictionary* cookieDictionary1 = [[NSUserDefaults standardUserDefaults] valueForKey:[cookieDictionary objectATindex:i]];
        NShttpCookie *cookie = [NShttpCookie cookieWithProperties:cookieDictionary1];
        [[NShttpCookieStorage sharedhttpCookieStorage] setCookie:cookie];
    }
}

-(void)savehttpCookies
{
    NSMutableArray *cookieArray = [[NSMutableArray alloc] init];
    for (NShttpCookie *cookie in [[NShttpCookieStorage sharedhttpCookieStorage] cookies]) {
        [cookieArray addObject:cookie.name];
        NSMutableDictionary *cookieProperties = [NSMutableDictionary Dictionary];
        [cookieProperties setObject:cookie.name forKey:NShttpCookiename];
        [cookieProperties setObject:cookie.value forKey:NShttpCookieValue];
        [cookieProperties setObject:cookie.domain forKey:NShttpCookieDomain];
        [cookieProperties setObject:cookie.path forKey:NShttpCookiePath];
        [cookieProperties setObject:[NSnumber numberWithUnsignedInteger:cookie.version] forKey:NShttpCookieVersion];
        [cookieProperties setObject:[[NSDate date] dateByAddingTimeInterval:2629743] forKey:NShttpCookieExpires];

        [[NSUserDefaults standardUserDefaults] SETVALue:cookieProperties forKey:cookie.name];
        [[NSUserDefaults standardUserDefaults] synchronize];

    }

    [[NSUserDefaults standardUserDefaults] SETVALue:cookieArray forKey:@"cookieArray"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}
